## Scores

| Criterion | Score | Evidence |
|-----------|-------|----------|
| Token Efficiency | 7/10 | AWS SDK responses are generally well-structured with selective field support, though SES API responses can be verbose for batch operations and lack native field selection at the API level. |
| Programmatic Access | 8/10 | Strong programmatic access via REST API, official AWS SDKs in multiple languages (@aws-sdk/client-ses, @aws-sdk/client-sesv2), AWS CLI support, and numerous third-party integrations, though no MCP server or GraphQL interface. |
| Autonomous Auth | 9/10 | AWS IAM provides granular, scoped permissions for SES operations, supports API keys/credentials with test/production separation, enables autonomous agent authentication without human-in-the-loop, and is an industry standard. |
| Speed & Throughput | 8/10 | AWS SES is a managed service with reliable performance, supports bulk send operations for batching, has documented rate limits with configurable throughput, though network latency is inherent to cloud-based email services. |
| Discoverability | 7/10 | AWS documentation is comprehensive and well-organized with API reference, though no OpenAPI spec was found; predictable AWS API naming conventions and error messages aid discoverability. |
| Reliability | 8/10 | AWS SES includes API versioning, consistent JSON response schemas, documented SLA and status page, and supports idempotent operations through message IDs, providing high reliability for production use. |
| Safety | 7/10 | SES offers sandbox mode for testing without production impact, IAM-based access control for scope limitation, though it lacks built-in dry-run capabilities and undo operations are limited to bounce/complaint suppression. |
| Reactivity | 6/10 | SES supports SNS notifications for delivery events and bounce/complaint callbacks, enabling event-driven workflows, though native webhook support is limited and agents must implement polling for status checks. |

## Biggest Friction
